Simpler and more precise tools are needed to measure Taijin Kyofusho which is a culture-bound anxiety disorder in East Asian countries. This study aimed to develop and validate a short form and a computerized adaptive test (CAT) of Taijin Kyofusho Scale (TKS), as well as compare the measurement precision of the short form, the CAT version and its original version. Item Response Theory (IRT) method was used to develop static short form and to simulate CAT. The short form consisted of 12 items (a 61% reduction) and the CAT version consisted of average 11.72 items (a 62% reduction) from the original TKS, respectively. Both short form and CAT version have similar levels of accuracy and precision in comparison to the original scale at the group level. However, at the individual level, the CAT version can maintain a more consistent level of precision across the continuum of severity than the short form. The short form of the TKS is sufficient for an initial assessment or screening in the community population. And the CAT version of the TKS is more suitable for tailored treatments in the clinical practice, which could detect detailed changes in the severity of Taijin Kyofusho.

Based on person-organization fit and social exchange theory, this study investigates the effect of the needs-supplies fit of developmental job experience (DJE) on proactive behavior and explores the mediating role of affective organizational commitment (AOC). A lagged survey design in two-wave was used, and hypotheses were tested using polynomial regression and response surface analysis. The results show that different fit combinations between individuals’ needs for DJE and organizations’ supplies affect proactive behavior. Employees engaged in more proactive behavior when high-high fit (vs. low-low fit) and undersupply (vs. oversupply) were present. Furthermore, the effect of the needs-supplies fit of DJE on the different foci of proactive behavior is different. As hypothesized, the relationship between the needs-supplies fit of DJE and proactive behavior is mediated by AOC. The results of this study can deepen researchers’ understanding of the role of DJE in employees’ organizational, interpersonal, and personal proactive behavior and provide support for the effective mechanisms of DJE on proactive behavior based on social exchange theory and person-organization fit theory.

To address the relationship between the proportions of carbohydrates and fat and hyperglycaemia in the Chinese population. A cross-section research involving data from the China Health and Nutrition Survey in 2009, and nutritional status and health indicators were mainly focused. China. 8197 Chinese individuals aged over 16 years, including 1345 subjects who had a low-carbohydrate and high-fat diet, 3951 individuals who had a medium proportion of carbohydrate and fat diet, 2660 participants who had a high-carbohydrate and low-fat diet and 241 people who had a very-high-carbohydrate and low-fat diet. Subjects with the high-carbohydrate and low-fat diet were significantly associated with an increased risk of hyperglycaemia (OR: 1·142; 95 % CI: 1·022, 1·276) when compared with the individuals with the medium proportion of carbohydrate and fat diet. Meanwhile, people with a very-high-carbohydrate and low-fat diet had a higher risk of hyperglycaemia (OR: 1·829; 95 % CI: 1·377, 2·429). In contrast, the association between participants with a low-carbohydrate and high-fat diet and hyperglycaemia was NS (OR: 1·082; 95 % CI: 0·942, 1·243) with adjusting a series of confounding factors. Furthermore, people with a very-high-carbohydrate and low-fat diet were significantly associated with a higher risk of hyperglycaemia in the major energy levels and social characteristics subgroup. We found the high-carbohydrate and low-fat and very-high-carbohydrate and low-fat diets were significantly associated with a high risk of hyperglycaemia. And, the association between low-carbohydrate and high-fat diets and the risk of hyperglycaemia was NS.

Escherichia coli O157:H7 is an important foodborne pathogen that has become a major worldwide factor affecting the public safety of food. Bacteriophage has gradually attracted attention because of its ability to kill specific pathogens. In this study, a lytic phage of E. coli O157:H7, named FEC14, was isolated from hospital sewage. Transmission electron microscopy analysis showed that phage FEC14 had an isometric head 80 ± 5 nm in diameter and a contractile tail whose terminal spikes present an umbrella-like structure. Phage FEC14 revealed 158,639 bp double-stranded DNA, with the G+C content of 44.6%, 209 ORFs and four tRNAs. Genome DNA of FEC14 could not be digested by some endonucleases. Many of the features of phage FEC14 are very similar to those of the newly classified genus “Kuttervirus”, including morphology, genome size and organization, etc. Phage FEC14 is proposed to be a new isolate of genus “Kuttervirus” within the family Ackermannviridae, moreover, the endonuclease resistance of phage FEC14, has priority over other genera of bacteriophages for its use in biocontrol of foodborne pathogens.

Hardy kiwifruit ( ) has an extensive range of nutritional and bioactive compounds and has been valued as a great resource for kiwifruit breeding. A better understanding of the dynamic changes of the composition and accumulation of nutritional compounds during fruit development and ripening is required before genetic or cultural improvements can be targeted. In the present study, the phytochemical analysis of two cultivars 'Yilv' and 'Lvmi-1' showed that they comprised different morphology, with a higher fruit diameter while a lower vertical fruit diameter of 'Lvmi-1' compared with 'Yilv'. The antioxidant capacity of both cultivars decreased during the maturity time and showed no significant difference between them. Furthermore, although glucose gradually increased during the maturity time, the predominant sugar composition was speculated to be fructose in 'Lvmi-1' fruit while sucrose in 'Yilv' fruit at the early fruit developmental stages. Moreover, the predominant acids in 'Yilv' and 'Lvmi-1' were citric acid followed by quinic acid, malic acid, and oxalic acid. The expression of sugar- and starch-related genes encoding the crucial enzymes suggested different changes in 'Yilv' and 'Lvmi-1'. Notably, a subsequent correlation analysis showed a significant positive correlation between sucrose phosphate synthase (SPS) expression and glucose in 'Yilv', fructokinase (FK) expression, and starch content in 'Lvmi-1', implying their vital roles in sugar and starch accumulation. By contrast, a significant negative correlation between FK expression and fructose in 'Lvmi-1' fruit was observed. In summary, our results provide supplementary information for the dynamic changes of nutritional compounds and antioxidant capacity during hardy kiwifruit maturity time and give a clue for exploring the mechanism of sugar and starch accumulation in hardy kiwifruit.

Background. We aimed to investigate the expression of the hyaluronan-mediated motility receptor (HMMR) gene in hepatocellular carcinoma (HCC) and nonneoplastic tissues and to investigate the diagnostic and prognostic value of HMMR. Method. With the reuse of the publicly available The Cancer Genome Atlas (TCGA) data, 374 HCC patients and 50 nonneoplastic tissues were used to investigate the diagnostic and prognostic values of HMMR genes by receiver operating characteristic (ROC) curve analysis and survival analysis. All patients were divided into low- and high-expression groups based on the median value of HMMR expression level. Univariate and multivariate Cox regression analysis were used to identify prognostic factors. Gene set enrichment analysis (GSEA) was performed to explore the potential mechanism of the HMMR genes involved in HCC. The diagnostic and prognostic values were further validated in an external cohort from the International Cancer Genome Consortium (ICGC). Results. HMMR mRNA expression was significantly elevated in HCC tissues compared with that in normal tissues from both TCGA and the ICGC cohorts (all P values <0.001). Increased HMMR expression was significantly associated with histologic grade, pathological stage, and survival status (all P values <0.05). The area under the ROC curve for HMMR expression in HCC and normal tissues was 0.969 (95% CI: 0.948–0.983) in the TCGA cohort and 0.956 (95% CI: 0.932–0.973) in the ICGC cohort. Patients with high HMMR expression had a poor prognosis than patients with low expression group in both cohorts (all P<0.001). Univariate and multivariate analysis also showed that HMMR is an independent predictor factor associated with overall survival in both cohorts (all P values <0.001). GSEA showed that genes upregulated in the high-HMMR HCC subgroup were mainly significantly enriched in the cell cycle pathway, pathways in cancer, and P53 signaling pathway. Conclusion. HMMR is expressed at high levels in HCC. HMMR overexpression may be an unfavorable prognostic factor for HCC.

Andrographis paniculata is a plant of the Acanthaceae family and its primary bioactive constituent, andrographolide, exhibits a broad spectrum of pharmacological activities and notable clinical efficacy. However, its poor solubility and limited bioavailability pose significant challenges for therapeutic applications. To overcome these limitations, researchers have synthesized andrographolide sulfonates by reacting andrographolide with ethanol and sulfuric acid. This sulfonated derivative significantly enhances water solubility and bioavailability while retaining key pharmacological properties such as anti-inflammatory and antiviral activities. As a representative formulation, Xiyanping injection has been widely employed in the treatment of respiratory infections, pneumonia, and related conditions, playing a critical role during the COVID-19 pandemic. Despite its widespread application, there has yet to be a comprehensive review of its chemical composition and pharmacological mechanisms. Additionally, the safety of Xiyanping injection remains a topic of some debate. This review systematically examines the chemical composition, pharmacological activities, clinical applications, and adverse reactions of andrographolide sulfonates and their formulation in Xiyanping injection to provide a scientific basis for further research and applications, while also offering valuable insights for the development of similar sulfonated drugs.

Quantitative precipitation forecast (QPF) verification stands out as one of the most formidable endeavors in the realm of forecast verification. Traditional verification methods are not suitable for high-resolution forecasting products in some cases. Therefore, the SAL (structure, amplitude and location) method was proposed as a method of object-based spatial verification that studies precipitation verification in a certain range, which is combined with factors including structure, amplitude and location of the targets. However, the setting of the precipitation threshold would affect the result of the verification. This paper presented an improved method for determining the precipitation threshold using the QPF from ECMWF, which is an ensemble forecast model and three-source fusion product that was used in China from 1 July to 31 August 2020, and then the results obtained with this method were compared with the other two traditional methods. Furthermore, the SAL and the traditional verification methods were carried out for geometric, simulated and real cases, respectively. The results showed the following: (1) The proposed method in this paper for determining the threshold was more accurate at identifying the precipitation objects. (2) The verification area size was critical for SAL calculation. If the area selected was too large, the calculated SAL value had little significance. (3) ME (Mean Error) could not identify the displacement between prediction and observation, while HSS (Heidke Skill Score) was sensitive to the displacement of the prediction field. (4) Compared with the traditional verification methods, the SAL method was more straight forward and simple, and it could give a better representation of prediction ability. Therefore, forecasters can better understand the model prediction effect and what needs to be improved.

Due to its wide distribution, the long‐distance oil and gas pipeline will inevitably pass through the landslide risk area. This study aims to investigate the impact of landslide geological disasters on oil and gas pipelines, particularly focusing on the deformation characteristics of pipelines under various landslide dip angles. To achieve this, a large physical simulation platform was designed and established as part of the methods used to replicate the effects of landslide geological disasters on oil and gas pipelines. Experiments were conducted at different dip angles, monitoring and analyzing changes in stress and strain within the pipeline, as well as soil displacement. Based on the experimental results, we draw the following conclusions: (1) the bending process of the pipeline can be divided into slow‐bending stage, constant‐speed bending stage, and accelerated‐bending stage. (2) The tensile strain is produced back to the impact direction of landslide; the compressive strain is produced facing the direction of landslide. At the point with the largest impact force of the landslide, when the dip angle of the landslide is 38°, the rate of slow increase is the greatest in the four stages, which is about 77 times that at a slope of 10° (3) At the same point, with the increase of the dip angle, stress is also gradually increasing. When the slope reaches the angle posing a landslide hazard, the maximum rate of change of stress is about 26.9 × 10−6 kPa/s. (4) At the centre of the pipeline, the strain difference between the back and facing the direction of the landslide increases continuously. These experimental results have obtained the pipeline deformation law in the whole process of pipeline landslide disaster, which can provide great help for the monitoring and early warning of pipeline landslide disasters on site. This study investigates the impact of landslide geological disasters on oil and gas pipelines, focusing on pipeline deformation under varying landslide dip angles. A large physical simulation platform was used to replicate landslide effects, with experiments conducted at different dip angles to monitor stress, strain, and soil displacement. The results reveal distinct bending stages of the pipeline, significant variations in strain and stress with increasing dip angles.

IntroductionIt remains unclear whether kidney transplantation (KT) from hepatitis B surface antigen (HBsAg) +donors to HBsAg− recipients (D(HBsAg+)/R(HBsAg−)) provides comparable transplant outcomes without hepatitis B virus (HBV) transmission compared with D(HBsAg−)/R(HBsAg−) KT. Moreover, no consensus has been reached for standardised prophylaxis regimens to prevent HBV transmission after D(HBsAg+)/R(HBsAg−) KT. We developed stratified prophylaxis regimens, including pretransplant antiviral treatment of donors, and pretransplant hepatitis B vaccination and post-transplant antiviral treatment of recipients, based on donors’ and recipients’ HBV serological characteristics. However, the safety and efficacy of stratified prophylaxis regimens remains unknown.Methods and analysisWe are conducting a prospective, multicentre, observational study. Between September 2020 and December 2023, 100 cases of (D(HBsAg+)/R (HBsAg−)) KT will be recruited from four university-affiliated hospitals with a follow-up at least 2 years. They will naturally receive stratified prophylaxis regimens or routine prophylaxis based on clinical experience to compare the efficacy and safety of these two regimens in (D(HBsAg+)/R(HBsAg−)) KT. The primary outcome will be post-transplant HBV infection to evaluate safety, defined as post-transplant HBsAg−→+or HBV DNA−→+. The composite endpoint of prevention failure will be also an endpoint of safety (any one of HBsAg−→+, HBV DNA−→+, HB e antigen−→+, HB e antibody−→+ and HB c antibody−→+). The efficacy will be evaluated by transplant outcomes, including death-censored graft survival, patient survival, acute rejection, delayed graft function and kidney graft function.Ethics and disseminationThis study will be registered as a clinical audit at each participating hospital and has obtained approval from the Ethics Committee of West China Hospital (reference: 2020-683, 8 September 2020).Trial registration numberNCT04562051.
